摘要: 森林土壤有机碳库是全球碳循环的重要组成部分,其积累和分解的变化直接影响陆地生态系统的碳贮藏与全球的碳平衡.气候变化将影响植物光合作用及土壤有机碳的分解和转化过程,进而影响森林土壤有机碳贮量及土壤碳动态.温度、降水、大气CO2浓度等气候因子对森林土壤碳贮藏均具有重要影响.了解气候变化对森林土壤有机碳贮藏的影响有助于人们科学管理森林碳库以及进一步寻找缓解气候变化的可行途径.为此,本文综述了森林土壤有机碳贮量的分布以及升温、降水变化和大气CO2浓度升高对森林土壤有机碳贮藏影响的国内外研究进展,并提出了有关的研究展望.

Abstract: Forest soil organic carbon is an important component of global carbon cycle, and the changes of its accumulation and decomposition directly affect terrestrial ecosystem carbon storage and global carbon balance. Climate change would affect the photosynthesis of forest vegetation and the decomposition and transformation of forest soil organic carbon, and further, affect the storage and dynamics of organic carbon in forest soils. Temperature, precipitation, atmospheric CO2 concentration, and other climatic factors all have important influences on the forest soil organic carbon storage. Understanding the effects of climate change on this storage is helpful to the scientific management of forest carbon sink, and to the feasible options for climate change mitigation. This paper summarized the research progress  about the distribution of organic carbon storage in forest soils, and the effects of elevated temperature, precipitation change, and elevated atmospheric CO2 concentration on this storage, with the further research subjects discussed.
